Answer 1

如果resetApp()不起作用，您可以尝试将其添加为DesiredCapabilities对象的功能

DesiredCapabilities capabilities = DesiredCapabilities.android();
capabilities.setCapability(MobileCapabilityType.NO_RESET, false);
capabilities.setCapability(MobileCapabilityType.FULL_RESET, true);

这两行将重置您的应用程序，这是文档http://appium.io/docs/en/writing-running-appium/other/reset-strategies/#reset-strategies
